NiFe2O4 nanocubes anchored on reduced graphene oxide cryogel to achieve a 1.8 V flexible solid-state symmetric supercapacitor
Chemical Engineering Journal(2019)
摘要
•A two-step hydrothermal strategy is adopted to transform Ni3[Fe(CN)6]2 to NiFe2O4.•NiFe2O4@rGO slice is prepared as electrode for flexible symmetric supercapacitor.•NiFe2O4@rGO electrode shows excellent specific capacitance and cycling stability.
